  Best Cyclotron Systems Inc (BCSI) has been established in Springfield, Virginia, US, for the design and production of commercial cyclotrons. The company is a subsidiary of Best Medical International renowned in the field of medical instrumentation and radiation therapy. Cyclotrons are manufactured and tested at Best Theratronics, Ottawa. BCSI is initially focusing on three different energy cyclotrons. All have four radial sectors with two dees in opposite valleys and simultaneous beam extraction on opposite lines. The BEST14p is designed for fixed 14 MeV extraction 100 μA internal upgradable to 400 μA external ion source for PET isotopes and 99mTc production. The BEST35p is designed for variable energy extraction up to 35 MeV and combined current in excess of 1.5 mA. The BEST70p is designed for variable energy extraction up to 70 MeV with a combined current of 800 μA. It may be used as injector to a post-accelerator simultaneously with isotope production. BEST70p is most challenging given its present state of the art design. Design goals are total H vacuum or e.m. losses ≤2%; dee voltage increasing with radius from 60 kV to 81 kV; extracted beam emittance <4π mm mrad.
